Embodiment Construction
[0034] The present invention will be further described in detail below in conjunction with the drawings and embodiments, but it is not used as a basis for any limitation on the invention.
[0035] As shown in the figure, a non-road diesel engine body is integrally cast with a rear gear plate 34 at the rear end of the diesel engine body, and a crankshaft mounting hole 1 is arranged at the lower part of the front of the rear gear plate, and the crankshaft mounting hole 1 is the diesel engine body Through hole; a crankshaft installation platform is provided on the front of the rear gear plate at the periphery of the crankshaft installation hole. The crankshaft installation hole here is a semicircular hole arranged on the diesel engine body, which is formed together with the semicircular hole on the bearing cover after the crankshaft is installed. Complete crankshaft mounting holes. see figure 1 , in this embodiment, the main bearing cap 8 is installed on the main bearing cap in...

A non-road diesel engine body, a rear gear plate is integrally arranged at the rear end of the diesel engine body, a crankshaft installation hole is arranged on the rear end gear plate, and an air compressor installation hole is arranged on the left side of the crankshaft installation hole; There is a camshaft installation hole on the upper left side of the hole, and there is a corresponding installation platform on the periphery of almost every installation hole. On the right side of the crankshaft installation hole, there is an idler gear shaft I installation platform; on the front of the rear gear plate A rear-end gear chamber cover installation platform is arranged on the periphery, and the rear-end gear chamber cover installation platform is processed with a rear-end gear chamber cover installation sealing plane and a plurality of rear-end gear chamber cover fixing holes. The main power input interface and transmission mechanism are arranged at the rear end of the diesel engine body, which can effectively reduce the torsional vibration of the crankshaft, reduce the vibration and noise of the whole diesel engine, and has a simple structure and convenient assembly.
Description
technical field [0001] The invention belongs to the technical field of internal combustion engines, in particular to a non-road diesel engine body. Background technique [0002] Internal combustion engines (internal combustion engines for short) are divided into two-stroke engines and four-stroke engines according to different strokes. Two-stroke engines have the advantage of simple structure, but at the same time, they also have fatal shortcomings such as low combustion efficiency, high fuel consumption, and large pollution; and Compared with two-stroke engines, four-stroke engines are more widely used because of their obvious advantages such as high combustion efficiency, low fuel consumption, more energy saving and environmental protection. The diesel engine (referred to as non-road diesel engine) used on non-road mobile machinery is mainly a four-stroke engine. [0003] At present, non-road diesel engines generally use gear transmission, chain transmission or belt trans...
